Grating Transition Radiation - a new source of quasi-monochromatic radiation
We have observed transition radiation at optical wavelengths, emitted by 3-13 MeV electrons interacting with a diffracting grating. Near the direction of specular reflection we observed broad-band radiation with the same properties as optical transition radiation from a flat surface. In addition, at large angles with respect to this direction and for low angles of incidence of the electrons on the grating surface, we observed emission quasi-monchromatic radiation. This Grating Transition Radiation may offer a new method for production of quasi-monchromatic radiation in the far infrared to mm wavelength range.
